[0036] In this embodiment, a positioning assembly is provided on the bracket 70. The arrangement of the positioning assembly enables the driving device 50 to stop after the shoe tray 301 reaches the second position without pausing.

[0037] In this embodiment, the positioning assembly includes an air gripper device 901, and the air gripper device 901 includes an air gripper cylinder and an air gripper. The shoe tray 301 is provided with a second protrusion 3012, and the air gripper positions the shoe tray 301 by clamping the second protrusion 3012. Specifically, the air gripper is driven by an air gripper cylinder driver, and two independent left and right pistons are installed in the cylinder body of the air gripper cylinder, and each piston is connected to an external air gripper, so the movement of each piston represents the movement of a single air gripper. The air gripper device 901 has two strip-shaped air grippers on the left and right that clamp the second protrusion 3012 of the shoe tray 301 to achieve the positioning of the shoe tray 301.

[0038] In this embodiment, the positioning assembly also includes a blocking block 902, which is fixed at the end of the guide portion 80; further, the bracket 70 is provided with a shielding portion (not shown in the figure), and the shielding portion is provided above the claw device 60 and the positioning assembly, and the shielding portion is provided to prevent the glue in the station body 10 from falling onto the claw device 60 and the positioning assembly; further, an inclined surface 401 is provided at one end of the guide rail 40 close to the entrance, and the setting of the inclined surface 401 facilitates the shoe tray 301 to enter the guide rail 40 from the entrance of the station body 10.

[0039] In this embodiment, in order to increase the spraying efficiency in the station body 10, two entrances to the station body 10 are provided, and two workstations are provided in the station body 10. Each workstation is provided with a guide rail 40, a driving device 50, a clamping device 60, a bracket 70, a guide part 80, a positioning assembly and a shielding part.

[0040] The material conveying device of the sole spraying workstation proposed in the utility model has the following working principle:

[0041] First, the conveyor belt 20 outside the station body 10 is responsible for conveying the tray assembly 30. When the tray assembly 30 is transported to the front of the entrance of the station body 10, the lifting cylinder 304 causes the entire tray assembly 30 to rise. When it rises to the point where the bottom surface of the shoe tray 301 and the upper surface of the guide rail 40 are on the same horizontal line, the motor 303 of the conveying device starts to operate, so that the conveyor belts 305 at both ends of the conveying base plate 302 drive the shoe tray 301 on the conveying base plate 302 to move toward the guide rail 40, and the shoe tray 301 enters the head end of the guide rail 40, that is, the first position.

[0042] At this time, the rodless cylinder starts to operate, and the slider of the rodless cylinder moves toward the entrance direction, and drives the connected claw device 60 to move toward the entrance direction. The rotating part 6022 of the claw block 602 first touches the first protrusion 3011 of the shoe tray 301. Since the rodless cylinder is driven outward at this time, the rotating part 6022 is subjected to the inward force of the first protrusion 3011 and rotates inward. The first protrusion 3011 enters between the pushing part 6021 and the rotating part 6022 in the claw block 602, and the rotating part 6022 also returns to its original state under the action of the torsion spring. Then, the rodless cylinder changes the driving direction and drives from the outside to the inside. At this time, under the drive of the rodless cylinder, the rotating part 6022, which can only rotate in one direction, pushes the first protrusion 3011 to move inward, that is, the entire shoe tray 301 slides inward from the first position on the guide rail 40 to the designated second position.

[0043] After reaching the designated second position, the shoe tray 301 is positioned by the positioning assembly, and the spraying mechanism performs spraying. After the spraying is completed, the rodless cylinder drives from the inside to the outside, and the push portion 6021 of the claw block 602 pushes the first protrusion 3011 to move outward, that is, the entire shoe tray 301 slides outward and returns from the second position on the guide rail 40 to the first position. After returning to the first position, the conveying device outside the entrance is restarted, and the shoe tray 301 returns to the conveying base plate 302. At this time, the shoe tray 301 and the conveying base plate 302 begin to descend under the action of the lifting cylinder 304. At the beginning of the descent, the shoe tray 301 breaks free from the restriction of the claw block 602, and the rodless cylinder connects the claw device 60 to return to the original position in the station body 10, and the entire tray assembly 30 finally returns to the conveyor belt 20 and is transported to the next process station on the conveyor belt 20.

[0044] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
